GRX1 Chapter 1

External Radio Antenna Connector

The UHF and SS antennas connect to the external antenna connector under the GRX1 housing
( Figure 1-7 ). Both modem antenna types include support for a GSM modem.
The modem antenna depends on the type of modem in-stalled in the receiver:

UHF: Uses a BNC RF connection and comes in three versions: 410-440MHz ( p/n
30-070003-01 ) and 440-470MHz ( p/n 30-050503-01 ).

Spread Spectrum: Uses a reverse polarity TNC RF connection and comes in one version:
( p/n 30-030012-01 ).

Connector

The bottom connector ( Figure 1-8 ) connects the receiver to either a standard 5/8''thread
pole/adapter or the quick disconnect ( see "The quick disconnect adapter" on page 1-22 for
details ).
